Question

我有一个csv文件，其中包含大约380个名字，如下所示：

John Smith
Alert Johnson
Corey Johnson

等等

我能够导入第一行并将其打印到图像上。但是，我想要做的是能够循环它并读取csv文件中的所有名称，然后在图像上打印每个名称。有380个名字，应该有380个带有名字的图像。

基本上我想循环它，直到它读取CSV文件中的所有名称并为每个名称保存图像文件。

有人可以帮助我如何让它循环读取csv上的所有名字吗？

    import PIL
    from PIL import ImageFont
    from PIL import Image
    from PIL import ImageDraw
    import ImageFont, ImageDraw
    import csv
    import sys



    #opens csv file and reads the first line. Using rstrip to get rid of special character at end
    with open('Names.csv', 'rU') as f:
            for name in f:
        names = f.readline().rstrip()
            names2 = f.readline().rstrip()


    #font and size on local machine
    font = ImageFont.truetype("/Library/Fonts/Microsoft/Arial.ttf", 150)


    #This is the text it will print.
    text = names


    #color of text = black
    tcolor = (255,0,0)


    #opens image in the same folder
    img = Image.open("Certificate.jpg") #opens image in the same folder


    #gets the height and width of the jpg
    width, height = Image.open(open("Certificate.jpg")).size


    #defining "draw" to draw onto image
    draw = ImageDraw.Draw(img)


    #define variables x = width and y = height
    text_x, text_y = font.getsize(text)


    #find the middle of width using this equation and store into "x"
    x = (width - text_x)/2


    #find the middle of height using this equation and store into "y"
    y = (height - text_y)/2


    #calls "draw" and writes "text" using middle of jpg
    draw.text ( (x,y), text, font=font, fill=tcolor)


    #saves image
    img.save("test.jpg")

我得到的错误：文件“full2.py”，第14行，in names = f.readline（）。rstrip（） valueError：混合迭代和读取方法会丢失数据

我可以使用While代替For。但是，我不知道如何实现While循环以保持读取行并打印/保存图像。

你应该使用for循环遍历每一行，例如for name in f:

    import PIL
    from PIL import ImageFont
    from PIL import Image
    from PIL import ImageDraw
    import ImageFont, ImageDraw
    import csv
    import sys



    #opens csv file and reads the first line. Using rstrip to get rid of special character   at end
    with open('Names.csv', 'rU') as f:
        for name in f: 
           #need to put all the statements below in this code block.

如何多次循环此python代码
